准备工作
1.准备一个docker.service文件
内容如下：
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock --selinux-enabled=false --default-ulimit nofile=65536:65536
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target假定安装包和docker.service文件以及各种镜像包都在/home/carrot/docker中
正片开始
进入位置
cd /home/carrot/docker解压
tar -zxvf docker-24.0.7.tgz复制
sudo cp docker/* /usr/bin
sudo cp docker.service /etc/systemd/system/赋予权限
sudo chmod +x /etc/systemd/system/docker.service开启docker并并设置开机自启动
sudo systemctl daemon-reload
sudo systemctl start docker
sudo systemctl enable docker.service收尾
将准备好的镜像包导入（以ubuntu镜像包为例）注意xxx.tar 是通过其他服务器执行docker save获取的
sudo docker load -i xxx.tar使用docker权限不足时
# 添加docker用户组，一般已存在，不需要执行
sudo groupadd docker
# 将登陆用户加入到docker用户组中
sudo gpasswd -a $USER docker
# 更新用户组
newgrp docker
# 以上操作不行就重启 （慎用）
sudo reboot镜像导入完成后删除多余文件
cd ..
rm -r docker
